Split from mod_http2 :: HowTo & Info & Tips

I have problems...

I added
Code:
LoadModule http2_module modules/mod_http2.so
<IfModule http2_module>
    ProtocolsHonorOrder On
    Protocols h2 http/1.1
</IfModule>


When I open http://mydomain.com/ the indicator (Chrome browser) shows: NOT SPDY-enabled.

When I open https://mydomain.com/ the Chrome browser shows: ERR_SPDY_INADEQUATE_TRANSPORT_SECURITY
I have working domain ssl certifiacate on mod_ssl.

What am I doing wrong?

You are using the latest Chrome ?

If you point your browser at a h2 server with inappropriate ciphers, you will get the obscure warning like INADEQUATE_SECURITY and the browser will simply refuse to continue.

Try the advised/recommended cypher suites to be used at https://www.apachelounge.com/viewtopic.php?p=31842
